SYRINGE.

SPECIFICATION forming part of Letters Patent No. 716,240, dated December 16, 1902.

Application filed April 25, 1902. Serial No. 104,603. (No model.) i

T owl whom it may concern:

Be it known that I, THOMAS L. JONES, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of treated; and my object is to produce an efficient device of this characterof simple, cheap, and durable construction,

To this end the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that it maybe fully understood reference is to be had to the accompanying drawings, in which-e Figure 1 represents a side elevation of a syringe embodying my invention. Fig. 2 is a perspective View of the syringe-nozzle.

In the said drawings, ldesignates a receptacle, preferably in the form of an inverted hot-water bag, the same having the usual loop 2, by which it is suspended from a hook or other support, and a neck 3, through which the water is introduced in the customary manner.

In lieu of the customary screw-plug for closing the opening of the bag I employ a tubular plug 4, having a flanged extension 5, to which is secured in any suitable manner a flexible rubber tube 6 of the required length and provided with a clamp or valve, such as shown at 7. This tube at its lower end is connected to the short hard-rubber or metallic tube 8, containing a check-valve 9, which opens under pressure of water from the bag, but closes against pressure toward the latter. The opposite end of said tube 8 is connected to one end of a compressible bulb 10, the opposite end of said bulb being connected to a short tube 11, containing a check-valve 12,

and connected at its opposite end to the tubular nozzle 13, said nozzle being composed of glass, hard rubber, orequivalent material. This nozzle l3tis open at its front end, the opening being preferably in the form of per nozzle and provided at diametrically opposite points with ears or lugs 17, between which are mounted and pivot-ally secured a pair of levers, said levers being composed, preferably, of spring-wire bent to form the loopjaws 18 of proper form and proportion to fit snugly and lie Wholly within grooves 15 and arms 19, having enlargements 20 at their rear ends and formed, preferably, by bending the rear ends of the Wires. To actuate these 1evers, I provide a sliding collar 21 upon the nozzle rearward of band 16, and said collar is formed with a pair of perforated cars 22, which slidingly engage lever-arms 19. The parts are so proportioned and arranged that when the sliding collar occupies its rearmost position, as shown, the jaws of the levers are disposed their greatest distance apart, forward movement of said collar until it is arrested by said band being attended by inward movement of said jaws, such movement terminating only when they lie wholly within or flush with the external surface of the nozzle, so as to offer no obstruction to the free insertion of the latter into or its withdrawal from the cavity.

In practical operation after the bag is charged with Water the nozzle,with the jaws 18 occupying grooves 15, is inserted into the cavity and then valve 7 is opened to permit water to flow into the bulb, the latter being alternately compressed and released in the usual manner to effect the forceful ejection of the water from the nozzle, and owing to the fact that this nozzle is perforated instead of having the usual large opening at the end it is obvious that the water will be more thoroughly distributed and the walls of the cavity more reliably cleansed or mediciually treated and in this connection it will be notedthat the use of check valves at opposite sides of the bulb insures the ejection of practically the same volume of water with each compression of the bulb, because it prevents the water backing from the nozzle into the bulb or from the latter into the tube 6.

Should it be of importance that the entire area of the cavity be treated, the operator will before ejecting the fluid slide collar 21 rearward upon the nozzle, this action forcing jaws 18 apart to distend the cavity, and thus give more perfect access to its entire surface.

After the parts have been thoroughly treated collar 21 is slid forward, so as to dispose the jaws 18 close to the nozzle, but without disposing them in the grooves in order to avoid any chance of pinching the walls of the cavity. As thus arranged the nozzle can be freely Withdrawn after valve 7 has been closed.

From the above description it will be apparent thatI have produced a syringe of simple, durable, and cheap construction which embodies the features of advantage enumerated as desirable in the statement of invention and which may obviously be modified in some particulars without departing from the spirit and scope or sacrificing-any of the advantages of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. A syringe, comprising a water vessel, a compressible bulb, a tube connecting the vessel and the bulb and provided with a controlling-valve, a nozzle connected to the opposite end of the bulb and provided with external grooves at diametrically opposite points, and

levers mounted on the nozzle and embodying jaws adapted at times to occupy said grooves.

2. A syringe, comprising a water vessel, a compressible bulb, a tube connecting the vessel and the bulb and provided with a controlling-valve, a nozzle connected to the opposite end of the bulb and provided with external grooves at diametrically opposite points, levers mounted on the nozzle and embodying jaws adapted at times to enter said grooves, and means for operating and securing said levers at the desired point of adjustment.

3. A syringe, comprising a water vessel, a compressible bulb, a tube connecting the vessel and the bulb and provided with a controlling-valve, a nozzle connected to the opposite ends of the bulb and provided with external grooves at diametrically opposite points, levers mounted on the nozzle and embodying jaws adapted at times to occupy said grooves, and arms extending at an angle to said jaws, and a sliding collar mounted on the nozzle and provided with perforated ears engaging said arms.

In testimony whereof I affix my signature in the presence of two witnesses.

THOMAS L. JONES.
